Really even after the spark plug shooter heads to. Sure the 5.4 has more at peak but ill bet down in the useable ranges the 351 is right with it if not ahead,
I am sure the shorter stroke of the 351 really helps with the bottom end torque.
2v 5.4 has 350 lb-ft at 2500, I have been towing with one for 14 years. With the od off it runs around 2700rpm, so as it pulls down it pulls into its power band.
